I'm afraid it's now come down to looks rather than quality nowadays. Granted HE-400's are ugly as sin IMHO, but HFI's are decent. I'm not going to lie though, Beats do look pretty snazzy and I want to get a broken pair of Studios and put some DT 770 Drivers in them if I can, or even scrap out my 580's or buy some M50's and put those drivers in some Beats.
Although I really don't care for the look of Beats myself, that's a pretty neat idea. Could have an awful lot of fun messing with people like that :)
